EU and NATO on New Division of Labor — Why Europe's Security Council Still Cannot Establish Defense

Ursula von der Leyen announced a European Security Council, an emergency protocol against hybrid attacks, and a new instrument for strategic enablers on September 16, 2026. This sounds like a European response to Russian drone violations, acts of sabotage, and the announced reassessment of American troop presence. However, the crucial point lies in the difference between political coordination and military capability. Brussels is designing new bodies while Europe may still need around 500 billion euros just to replace the most important American strategic enablers.

A Security Council with Old Problems

The planned European Security Council is to convene as a special composition of the European Council and will include not only EU member states but also Ukraine, the United Kingdom, Norway, and Canada. This would institutionalize a political reality that already exists: Volodymyr Zelensky is regularly invited to European summits, London and Oslo are indispensable for continental security, yet they are not part of the EU. Therefore, the proposal is more sensible than the usual Brussels symbolic politics. However, it does not eliminate a decision-making problem.

The idea dates back to Emmanuel Macron in 2017 and the Franco-German Meseberg Declaration of 2018. The urgency is new, not the concept. Von der Leyen did not mention a start date or specific responsibilities. This is where the institutional weakness begins. An additional format can promote a common perception of threats; however, it can also double the already complicated landscape of the European Council, NATO, Coalition of the Willing, and bilateral coalitions. Nathalie Tocci from the Istituto Affari Internazionali warned accordingly that the Security Council is not a panacea: consensus will still be required there.

The Emergency Protocol alongside Article 4

Politically more explosive is the proposal for an Emergency Security Protocol. It is intended to apply in incidents that fall below an open armed attack but threaten national security and territorial integrity. The EU would thus practically underpin its mutual assistance clause with a procedure. If the protocol is triggered, all member states are to come together, coordinate a European response, deter further escalation, and limit the consequences.

This is not irrelevant for sabotage, drone overflights, and attacks on critical infrastructure. NATO Article 4 already exists, but it requires political consultation among alliance members. The EU could also cover the special case of Cyprus, which is an EU member but not a NATO member. In early 2026, an Iranian-manufactured drone operation against a British airbase in Cyprus raised the question of how the mutual assistance clause should be practically activated. EU ambassadors subsequently conducted a simulation exercise.

However, a protocol is not yet a deterrent. Former NATO spokesperson Oana Lungescu noted that both organizations already have protocols and playbooks. Moscow will not be impressed by the existence of another document but by the credible prospect of costs. If the European response ultimately consists only of statements, sanction packages, or civil protection, it is legitimate but not a military substitute for NATO capabilities.

Strategic Enablers are the Real Test

Von der Leyen has therefore identified the right bottleneck: satellites, strategic airlift, air refueling, and reconnaissance. These capabilities are less visible than Leopard 2 tanks or Eurofighters, but they determine whether armed forces can operate over a longer period. The war in Ukraine has shown that precision effects, situational awareness, and logistics cannot be provided in isolation at the national level.

The new European Instrument for Strategic Enablers is intended to pool long-term investments and align them with NATO. The problem is the scale. Defense Commissioner Andrius Kubilius estimated in June that replacing American military assets in Europe would cost about 500 billion euros. Against this sum, a new financing instrument initially appears to be a political container, not a capability. It remains unclear which states will finance which satellites, tanker aircraft, or reconnaissance systems, who owns the data, and who makes the operational decision in a crisis.

Here, Europe's familiar pattern repeats itself. The EU can mobilize money and invent institutional names; however, it cannot dissolve national sovereignty in procurement and operational command through summit decisions. A European satellite network without shared data would be a prestige project. Joint tankers without secured maintenance and crew planning would be a fleet on paper. More defense spending will only create deterrence when it is translated into available, interoperable, and politically authorized systems.

The NATO Question Remains

Brussels explicitly emphasizes that the new architecture is to be in line with NATO. This is necessary but not automatically guaranteed. An EU mechanism alongside Article 4 can strengthen the European pillar but can also create jurisdictional conflicts. Who convenes the situation meeting? Who defines the threshold between sabotage and armed attack? Who speaks for Europe when London and Washington set different priorities?

NATO remains the foundation of collective defense, as an alliance spokesperson explained to Euronews. Precisely for this reason, the EU must precisely define its complementary function. Strategic autonomy does not mean replacing NATO with an EU shadow alliance. It means that European states can contribute more than political statements and additional orders within the alliance.

Conclusion

Von der Leyen's proposal is a necessary wake-up call, but it is not yet a Security Council and certainly not a defense capability. The European Security Council can improve consultations, the emergency protocol can shorten response times, and the enabler instrument can coordinate investments. However, without responsibilities, money in the order of hundreds of billions of euros, and binding national contributions, they remain three new labels on an old problem. Europe indeed needs its own structures because American support has become less certain. The bitter irony is: the more urgent European autonomy becomes, the less time remains for its Brussels institutionalization.
